wild, some cultivated on a small scale, the fruits varying 

 in size and color, all of value possibly for breeding pur- 

 poses. (Meyer's introductions.) 



Rhus sp. (Anacardiaceae . ) 40716. Seeds of a sumach from 

 near Yu yin chen, Kansu, China. "A sumach,, found on stony 

 mountain slopes, in ravines and on wild places; growing 

 into a tall shrub or small tree. Leaves large, light- 

 green, pubescent, winged. Fruits borne in large spikes; 

 berries coated with a sticky whitish wax which burns read- 

 ily. The Chinese do riot seem to utilize this wax in any 

 way. Of value as an ornamental park shrub for the mild 

 wintered sections of the United States." (Meyer's intro- 

 duction and description.) 



Rhus javanica L. (Anacardiaceae .) 40717. Seeds of a su- 

 mach from near Kwan yin tang, Shensi, China. "A sumach 

 with medium sized, glossy green leaves and reddish peti- 

 oles, growing into a tall shrub or even into a tre-e up to 

 60 feet high. Assumes most brilliant colors in fall. 

 Produces many spikes of reddish-bronze colored berries 

 which persist on the trees for a long time. On this su- 

 mach a gall insect makes its home, producing large inflat- 

 ed galls, which the Chinese utilize much for dyeing black. 

 The foreigners however, found out that they contain a 

 great percentage of tannin and used them for tanning pur- 

 poses, vast quantities being exported from Hankow espe- 

 cially, under the name of ' Chinese gall-nuts . ' This sumach 

 possibly might be cultivated on cheap lands in the South- 

 ern States for its gall production. It is not very par- 

 ticular as to soil requirements, but it loves good drain- 

 age. Care should be taken however, to keep it well under 

 control as it has decidedly weedy tendencies. Chinese 

 name Wu bei tzu shu, meaning 'Five folded seed tree.'"

Rosa spp. (Rosaceae. ) 40699-702, 40768. Seeds of roses 

 from Kansu, China. 40699, Rosa sweginzowii Koehne, "from 

 near San sze miau. A wild rose, resembling R. hugonis , of 

 very vigorous growth and having remarkably broad spines, 

 which vary much in size and in quantity on various speci- 

 mens. Found on rocky mountain slopes at elevations be- 

 tween 5000 and 8000 feet. Of value possibly as a factor 

 in hybridization experiments." 40700, "from near Chiao 

 tchwan chen. A very vigorously growing rose of climbing 

 habit, overrunning clumps of shrubbery. Bears very large 

 clusters of orange-red berries; foliage large, slightly
